Very interesting account of not so much the discovery of penicillin, but the monumental effort required by a somewhat overlooked group of scientists to scale-up production and test it during the shortages and frustrations of England during the second World War. Cheers to Florey, Chain, Heatley, the penicillin girls and others who brought us into the antibiotic era.
A wonderfully-written story of a series of essentially lucky accidents that ended up saving millions of lives.
This book was much harder to get into than I anticipated. Around chapter 8, the race to produce enough penicillin starts and things get interesting. But I still prefer Demon Under the Microscope, about the discovery of sulpha drugs.
